Q How to shift the elevation base point (e.g., add +1.50m to ground levels or pipe invert levels)?
A
Two options:
1. In Longitudinal design mode, open the “Span data” screen, copy ground levels to Excel, edit, and paste back, then run longitudinal calculation.
2. Export via [Options] – [Output network CSV datas], edit ground levels in Excel, import back, and run longitudinal calculation to update invert levels accordingly.
